theoretically it should have worked just by running the blu/white wire to the sub and solid blue to the power antena remote, but it wouldnt work, the sub would go off like 10 min after playing and the power antena wouldnt go up.

When I used a relay, it worked for a week, no it just makes everything go on and off every 1/2 sec. (really fast)

I don't know what is going on. this is my setup maybe someone can help me out.

Alpine 7874/ Alpine s603 Changer/ Rockford 400W amp

Head unit is hooked up with an adaptor, I matched all colors, all the connections are good. There are 2 remote wires, one for amp one for antena, both are connected to the right one. There is a 12v relay on the remote goin to the amp, the relay gets the power from the yellow wire (friend said to use that as power.)

Also, the yello wire came with a filter, (friend said not to use it, so i cut it off)

btw my friend is a pro car audio guy, he just moved to SC so he can't help me out.
